Offensive Security has released BackTrack 5 R3, an updated version of the project's Ubuntu-based distribution with a collection of security and forensics tools: "The time has come to refresh our security tool arsenal - BackTrack 5 R3 has been released. R3 focuses on bug fixes as well as the addition of over 60 new tools – several of which were released in BlackHat and Defcon 2012. A whole new tool category was populated - 'Physical Exploitation', which now includes tools such as the Arduino IDE and libraries, as well as the Kautilya Teensy payload collection. Together with our usual KDE and GNOME, 32/64-bit ISO images, we have released a single VMware Image (GNOME, 32-bit)."
BackTrack is an Ubuntu-based distribution with a collection of security and forensics tools. It was created by merging Auditor Security Linux with WHAX (formerly Whoppix).
